Doriopsilla albopunctata
A colorful dorid nudibranch with tiny white dots on raised tubercles.
The white-spotted sea goddess, *Doriopsilla albopunctata*, is a dorid nudibranch belonging to the family Dendrodorididae. This sea slug lives along the Pacific Coast of North America, ranging from Mendocino County, California, south possibly to Mexico’s Baja California Peninsula. Five other species closely resemble it and can be mistaken for it: *Doriopsilla bertschi*, *Doriopsilla davebehrensi*, *Doriopsilla fulva*, *Doriopsilla gemela*, and *Baptodoris mimetica*.
The animal can reach up to 60 mm (about 2½ inches) in length. Its body may be yellow, orange, or brown, but always features very small, opaque white dots. These dots sit on the tips of raised tubercles and also form rings around them. The rhinophores at the head are yellow or orange-yellow, while the gill rosette at the rear is white or pale yellow.
Its diet is not fully certain, partly because of the recent discovery of similar species. Past reports that it eats an orange sponge at Bahía de los Ángeles may actually refer to *Doriopsilla bertschi*. It has also been recorded feeding on the yellow boring sponge *Cliona californiana*.

Lore & Background
Doriopsilla albopunctata can grow as large as 60 mm. Its body may be yellow, orange, or brown, but always features very small opaque white dots. These dots are located on the tips of raised tubercles and in circles around the tubercles. The rhinophores on the head end are yellow or orange-yellow, while the gills, arranged in a rosette at the back, are white or pale yellow.
There are five other species that are quite similar to Doriopsilla albopunctata and can be confused with it: Doriopsilla bertschi, Doriopsilla davebehrensi, Doriopsilla fulva, Doriopsilla gemela, and Baptodoris mimetica. The diet of this species needs clarification in light of newly discovered species; reports may refer to related species. It has been reported to eat an orange sponge at Bahía de los Ángeles, but this is possibly a reference to Doriopsilla bertschi. It has also been reported to eat Cliona californiana, the yellow boring sponge.
Reader's Guide
Doriopsilla albopunctata is a well-known species along the Pacific Coast of North America, recorded from Mendocino County, California south to San Diego, and possibly extending to the Baja California Peninsula, Mexico. Its striking coloration and pattern of white dots make it a recognizable member of the Dendrodorididae family. However, its identification is complicated by the existence of five similar species, including Doriopsilla bertschi, Doriopsilla davebehrensi, Doriopsilla fulva, Doriopsilla gemela, and Baptodoris mimetica. The dietary habits of Doriopsilla albopunctata remain uncertain; earlier reports of it feeding on an orange sponge at Bahía de los Ángeles may actually refer to Doriopsilla bertschi. It has also been documented eating Cliona californiana, the yellow boring sponge. This uncertainty underscores the need for further study to clarify its ecological role and distinguish it from its close relatives.

What does Doriopsilla albopunctata look like?
The body is yellow, orange, or brown and studded with raised tubercles bearing very small opaque white dots, frequently ringed in little circles around each bump. Rhinophores are yellow or orange-yellow, and the gills are white or pale yellow.
Where can I find Doriopsilla albopunctata in the wild?
This species is found along the Pacific Coast of North America, from Mendocino County in California southward, with its range possibly extending to Mexico's Baja California Peninsula.
How large does Doriopsilla albopunctata grow?
Adults can reach a maximum of about 60 mm, which is roughly two and a half inches in length.
How do I distinguish Doriopsilla albopunctata from similar species?
Five closely related species—Doriopsilla bertschi, D. davebehrensi, D. fulva, D. gemela, and Baptodoris mimetica—are frequently mistaken for it. Careful attention to the exact arrangement of the tiny white dots on the tubercles, combined with body coloration, is needed to separate them.
